I love data. It is the life hacker's best friend.
The data shows, for example, that texting while driving is more dangerous than driving drunk. It doesn't feel that way, of course, but will you respect the data and stop, cold turkey?
The data shows that famous colleges underperform many cheaper, friendlier, smaller colleges. How much is your neighbor's envy worth?
These are just a few of the millions of examples of counter-intuitive data-driven findings. It took Galileo decades to persuade people the light objects fell as fast as heavy ones... even though he was busy dropping them off buildings for all to see.
